David Parry called this THE CULT OF EXTREMISM; it was delivered at THE EXTREMISTS CLUB on April 26, 2016. Actually, I was not in particularly ill-health as David said here, but my back had been giving me more problems than usual earlier in the week. By this time though, I was over the worst of it.
Although I had a few notes in front of me, this was totally unscripted, so there is no transcript, but see links below.
The speech includes a question and answer session.
